Free, curriculum-aligned Year 5 maths practice — factors and primes, fractions and decimals, percentages and volume — with a fresh weekly challenge and step-by-step lessons.
The core of the Australian Curriculum for Year 5 — all practised free on KAOO.
Finding factors and multiples, and identifying prime and composite numbers.
Multiplying and dividing by 10, 100 and 1000, including with decimals.
Adding and subtracting fractions, and decimals to thousandths.
Understanding percentages and connecting them to fractions and decimals.
Area of rectangles, volume of solids, and 24-hour time.
Reflections, rotations and translations, and interpreting data sets.
Year 5 introduces the topics children most often find tricky — fractions, decimals and percentages all at once. Taught visually and practised little and often, they become genuinely intuitive. Rushed or skipped, they become the gaps that haunt high-school maths.
Year 5 is the runway to the selective high school test (sat in Year 6) and many scholarship exams. A steady habit of weekly timed practice now means your child arrives at Year 6 already comfortable with problem-solving under time — not cramming at the last minute.
